Add comprehensive Ollama log checking and configurable LLM judge mode

Test case enhancements:
- TC-RUNTIME-001: Add startup log error checking (CUDA, CUBLAS, CPU fallback)
- TC-RUNTIME-002: Add GPU detection verification, CUDA init checks, error detection
- TC-RUNTIME-003: Add server listening verification, runtime error checks
- TC-INFERENCE-001: Add model loading logs, layer offload verification
- TC-INFERENCE-002: Add inference error checking (CUBLAS/CUDA errors)
- TC-INFERENCE-003: Add API request log verification, response time display

Workflow enhancements:
- Add judge_mode input (simple/llm/dual) to all workflows
- Add judge_model input to specify LLM model for judging
- Configurable via GitHub Actions UI without code changes
